ThermiSmooth is a laser treatment used to smooth lines and wrinkles, reverse signs of aging and lift sagging skin. It uses both radiofrequency and gentle heat to stimulate collagen production deep inside the skin. The procedure uses radiofrequency energy to heat the skin while also causing some of the collagen to shrink. This process allows the skin to become tighter and smoother. The body also produces new collagen to rejuvenate the skin on the face and other parts of the body.
